The document discusses acute herpetic gingivostomatitis caused by the herpes simplex virus type 1 (HSV-1). It notes that HSV-1 is highly prevalent, infecting over 70% of Americans, and transmission usually occurs in early childhood. Young children between ages 2-4 are most susceptible after maternal antibody levels decline. While many HSV-1 infections are asymptomatic, the most common clinical manifestation in young children is primary herpetic gingivostomatitis (PHGS), occurring in 25-30% of infected children. The virus spreads easily among young children through contact with saliva, toys, or utensils.

2. Introduction :
 The herpes virus is ubiquitous, passing
from person to person through
contaminated secretions or lesions. At
least 70% of the American population has
been infected, likely occurring in early
childhood (Murph & Grose, 1999).
Worldwide, the rate of infection is over
85% (Rosen & Ablon, 1997).

3. Cont ...
 After levels of passively acquired maternal
antibodies have diminished, infants and
young children are at increased risk for
acquiring infections. Sealander and Kerr
(1989) reported that children ages 2 to 4
are most susceptible to herpes simplex
virus (HSV) infections.

4. Cont...
 The majority of primary HSV-1 infections
are asymptomatic or mild enough to go
unrecognized (Amir, Harel, Smetana, &
Varsano, 1997; White, 1998).

5. Cont...
 the most frequent manifestation of initial
HSV-1 disease in young children is primary
herpetic gingivostomatitis (PHGS) (Amir et
al., 1997; Murph & Grose, 1999). This
occurs in 25-30% of affected children (Amir
et al., 1997).

6. Cont...
 The virus spreads easily among young
children through saliva (spit), shared toys,
drink cups, or eating utensils.
